Contributing to Hyperledger Grid
We welcome your help with Hyperledger Grid. Contributions from the development community help improve the design and capabilities of Hyperledger Grid. These contributions are the best way to make a positive impact on the project.
Ways you can contribute:
Bugs or issues: Report problems or defects found when working with Grid
Core features and enhancements for hyperledger/grid: Provide expanded capabilities or optimizations
Features and enhancements for hyperledger/grid-contrib: Contribute new example apps, demos, and smart contracts, or help with existing ones
Documentation: Improve existing documentation or create new information
Tests for events and results: Add functional, performance, or scalability tests
Hyperledger Grid issues are tracked in Github Projects (see Using Github Projects). Any unassigned items are probably still open. When in doubt, ask on the #grid chat channel about a specific issue (see Joining the Discussion).
The Commit Process
Hyperledger Grid is Apache 2.0 licensed and accepts contributions via GitHub pull requests. When contributing code, please follow these guidelines:
Fork the repository and make your changes in a feature branch
Include unit and integration tests for any new features and updates to existing tests
Ensure that the unit and integration tests run successfully.
Check that the lint tests pass.
Pull Request Guidelines
A pull request can contain a single commit or multiple commits. The most important guideline is that a single commit should map to a single fix or enhancement. Here are some example scenarios:
If a pull request adds a feature but also fixes two bugs, the pull request should have three commits: one commit for the feature change and two commits for the bug fixes.
If a PR is opened with five commits that contain changes to fix a single issue, the PR should be rebased to a single commit.
If a PR is opened with several commits, where the first commit fixes one issue and the rest fix a separate issue, the PR should be rebased to two commits (one for each issue).
Important: Your pull request should be rebased against the current master branch. Do not merge the current master branch in with your topic branch. Do not use the Update Branch button provided by GitHub on the pull request page.
Commit messages should follow common Git conventions, such as using the imperative mood, separate subject lines, and a line length of 72 characters. These rules are well documented in Chris Beam’s blog post.
Each commit must include a “Signed-off-by” line in the commit message (
commit -s). This sign-off indicates that you agree the commit satisfies the
Developer Certificate of Origin (DCO).
Commit Email Address
Your commit email address must match your GitHub email address. For more information, see https://help.github.com/articles/setting-your-commit-email-address-in-git/
Important GitHub Requirements
A pull request cannot merged until it has passed these status checks:
The build must pass on Jenkins
The PR must be approved by at least two reviewers without any outstanding requests for changes
